UNITED STATES PATENT OFFICE CONVEYER GUARD CLAMP"- Reginald C.A Lyons,Royal Oak, Mich. Application November 4, 1944, Serial No. 562,025

(Cl. 18S- 35) 4 Claims.

This invention relates to a conveyer guar clamp.

In modern plants considerable use is made of conveyer guards in assemblylines, etc. These guards prevent operators from getting in con'- tactwith the conveyers and also prevent accidents in that any parts thatmight fall off from conveyers are not damaged and do not fall onoperators.

It is an object of the present invention to provide a conveyer guardassembly which is inexpensive in construction and which lends itself toease of assembly and disassembly. With the present device the panelsthat go to make up the conveyer guards can also be shipped and stored inmuch less space than was previously necessary. Panels are always readyfor reuse in different assemblies which might be composed of differentcombinations of panels than the previous assembly. All together theparticular clamp to be disclosed here aifords great adaptibility in theuse of these conveyer guards. In addition it is an object of theinvention to provide a reinforcing means for the guards which affordsadditional protection in the event of unexpected loads or accidentalstrains to which the conveyer guards are subjected.

Other objects and features of the invention relating to details ofconstruction will be evident in the following description and claims.

In the drawings:

Fig. 1 illustrates a perspective View of the l parts of the clamp.

Fig. 2 is a sectional View illustrating the conveyer guard assembly.

Fig. 3 is a perspective View showing one corner of the assembly and therelationship of the parts therein.

Conveyer guards are quite frequently made up from panels composed ofreticulated material such as expanded metal, open mesh wire or somesimilar sheet metal with T-channels edging the sheets. As shown in Fig.3 the reticulated metal Il! has edging channels Il. The leg of the T,shown at l2, is composed of two portions which are welded or otherwisesecured to the opposite sides of the edge of the sheet Il).

In forming a conveyer guard these sheets or panels are arranged inangular relationship as shown, for example, in Fig. 2. Sheet |0a formsthe bottom and at right angles to the sheet Ia on either side are sheetslllb and lllc. The clamp used to hold these sheets together is formed ofparts 25| and 2l. Part 20 is shaped to correspond to the jformation oftwo T-channels arranged at right angles as shown in Fig. 2. Part 2| -hasa configuration on the other side -of-the T-channels. Part 20 has an endprojection 22 which is narrower than the general width of the part andhooked over as at 23. Part 2| has a similar extension 24 hooked as at25. These parts are complemental in that they iit together when theparts are assembled as shown in Fig. 3. Each is adapted to. pass throughan aperture 3G in the reticulated sheet IEI and hook over a margin ofthat aperture while fitting together with the corresponding portion ofthe other part of the clamp. After this assembly the other two ends ofthe parts 20 and 2| referred to as 3| and 32 are clamped togetherthrough a suitable aperture by bolt 33. Tightening this bolt 33 causes arm clamping action against the channels to hold the panels in properrelationship.

The panels can be readily disassembled or assembled and with thisarrangement they may be stored in a minimum of space. In addition withthe provision of the extensions 22 and 24 with the corresponding hookedportions 23 and 25 and the other ends 3| and 32 of the clamping membersthere is a reinforcing action in the holding of the reticulated membersl0 into the channels Il in case the spot welding proves defective.

I claim:

1. A conveyer guard assembly comprising strips of reticulated sheetmaterial, T-members edging said sheet material, and means to clamp saidT-members together whereby said sheets have an angular relation,comprising a first clamp member formed of strip material having a pro..jection at one end of narrower width than the remainder, a second clampmember having a similar projection arranged to intert with the flrstprojection, said projections being arranged to pass through and hookover a portion of said sheet material adjacent said T-members and tolock in position in adjoining relation, and releasable means to hold theother ends of the clamp members in place around said T-members I to lockthe same together.

2. A conveyer guard assembly comprising sheets of reticulated metaledged with sheet metal T- members welded in place, and means to fastensaid T-members together in angular relation comprising a. clamp formedof relatively stiff material shaped to accommodate the form of theadjoining T-members, and arranged in two parts, each of which has aportion to interflt with the other and pass around one of said T-membersthrough an aperture in the reticulated metal, and releasable means atthe other ends of the parts to lock the same together.

3. In a guard for a conveyer or the like, a pair of panels disposed inrelatively angular relationship with edges of the two panels lyingadjacent and substantially parallel with each other, an edge membersecured to each of the edges of the two panels, a pairA of eomplementalclamp members, one of said clamp members being shaped to embrace thesurfaces of the edge members which clamp member being shaped to embracethe surfaces of the edge members on the inside of said angle, at leastone of the panels having apertures therein, one end of each complementalclamp member having a hook formation, and said hook,

formations passing through an aperture in the said one panel fromopposite sides thereof in interfltting relationship t0 secure said endstogether and to` secure said ends to said panel and means for securingthe opposite ends of said complemental clamp members to the other panelto clamp the complemental .members around said edge members.

`4. In a guard fora conveyer .or the like, a pair of guard panelsdisposed in relatively angular relationship with edges Vof the twopanels adjacent and substantially parallel with each other, a hollowsheet metal edge Ymember secured to each of said adjacent edges of thetwo panels, a pair of complemental clamp members, one of said clampmembers being shaped to overlie surfaces of the edge members on theoutside of the angle formed by the two panels and having end portionsoverlying the outside surfaces of the panels inwardly of the edgemembers, the other complemental clamp member being shaped to overliesurfaces of the edge members on the inside of the angle formed by thepanels and having end portions overlying the panels inwardly of the edgemembers, and complemental hooks formed on one end of each complementalclamp member arranged to pass through and REFERENCES CITED The followingreferences are of record in the le `of this patent:
